AV-TEST Product Review and Certification Report – Mar-Apr/2020
During March and April 2020 we continuously evaluated 20 home user security products using their default settings. We always used the most current publicly-available version of all products for the testing. They were allowed to update themselves at any time and query their in-the-cloud services. We focused on realistic test scenarios and challenged the products against real-world threats. Products had to demonstrate their capabilities using all components and protection layers.
